The X-Men world turned upside down:
When the researchers put the gene for Magneto in zebrafish, a model organism for brain development, they found that the hybrid could alter complex behaviors. Using a genetic switch, the researchers made Magneto active in the zebrafish nerve cells that are involved in sensing touch. And, when they added a magnetic field, the fish upped the amount of time they coiled their tails, a touch-induced escape response.
